Base
Clean the adhesion base of loose dust and dirt. Before applying the plaster, wet the area so that is damp enough to be darker in colour.
Mixing
The liquid component is mixed prior to use. Five litres of liquid component is mixed with 25 kg of dry product, using a drill paddle for approx. 2 minutes. If necessary, the consistency is adjusted by adding water max. 1.5 litres per dose. Allow the plaster to stand for a few minutes and the mix again briefly. The workability time of finished Bedding mortar for high-performance concrete is approx. 2 hours.
Work instructions
In connection with Fescotop F90K High-performance concrete, the Bedding mortar for high-performance concrete is brushed in a carefully ground base that has been wetted the previous evening. The base must not have loose water! After liquid additions, one sack is enough for approximately 8-12m2 depending on the base.
Fescon Fescotop F90K High-performance concrete is spread according to separate instructions on the wet-on-wet principle on the Bedding mortar for high-performance concrete. The amount of the Bedding mortar for high-performance concrete for its part affects how soon lapping can be started. So, in addition to too small amounts, also too large amounts of Bedding mortar for high-performance concrete should be avoided.
